. The present invention relates to a device for safely operating,securing, and locking in various positions, windows, doors or the likewhich are adapted to be-moved either in the inward direction or in theoutward direction. So-called window stay devices for fixing a window orthe like in a partly open position, are. old.- The said stay devicescomprise a control rod or lever pivoted to the window frame or sash,respectively, or to an equivalent part, and provided with recesses, anda stopping member provided on the window sash or frame, respectively,oran equivalent part, the said stopping member being adapted to'cooperate withthe recesses of the rod in order'to retain the same.

The purpose of the invention is to obtain a stay of the kind in questionwhich also constitutes a window operating device and which is simple,consists of few, simple and little damageable parts, has no screws,springs, et cetera, and is easy to handle, and which, thus, may beoperated silently and easily with one hand only and which at the sametime resistant and durable.

The problem has been solved according. to the invention in such a waythat the stopping member is embodied as a rotatably mounted sleeve orthe like provided with a hole for the rod so that in an unsecuredposition the rod is guided in the sleeve: with only insignificant play,and the lower limiting portion of the hole is given a shape exactlyadjusted to co-operate with the recesses which here are provided on theunderside of the rod. Thus, the stopping engagement of the rod and thesleeveis produced by moving the rod downwards or by the rod falling dueto its own gravity. Its moving out of position and the operation'of'the'window can be effected with one hand only by grasping" the free end ofthe rod. Moreover, the rod is of such a length and the securing pointsof the. same and the sleeve are located in such a way on the respectiveparts that the most advantageous lever action is obtained,

respectively, so that due to co-operation of the device employed with aninwardly moving win- Figure 1 being a front view of part of the windowin closed position;

In Figures 4 and 5, which show the device mounted on an outwardly movingwindow, Figure 4 is likewise a cross section, and Figure 5 a frontsection; 7

Figures 6 and 7 show on a larger scale an embodiment of an operatinghandle and a partial view of the operating rod respectively, theoperating handle being embodied in another way.

I indicates the window sash, 2 the window frame, and 2a the boardedwindow sill. One end of an operating and control rod 3 is pivoted to thewindow frame (Figures 1 to 3) or the window sash (Figures 4 and 5)respectively, and extends through a hole 4 in a socket or sleeve 5 orthe like pivoted to the window sash or the window sill respectively, thesaid socket or sleeve forming a guide and stopping member for the rod.The size of the hole 4 is adjusted exactly to fit the rod 3, which inthe embodiment shown has a cylindric shape so that the rod only moveswith small play in the sleeve. The lower part (preferably half) of thehole has a rectangular shape; the lower edge portion 6 of the opening isadapted to engage recesses I on the underside of the rod in order to fixthe window in the desired position, and has a shape adjusted tofit therecesses. In the embodiment shown the recesses 1 are rectangular orapproximately rectangular, in axial section and the engagement portion 6has a corresponding shape so that a secure engagement is obtained.

At its free end the rod has an operating handle which may be shaped asan arched plate or arm 8 which serves as a finger grip and is detachablysecured (see particularly Figure 6) or as aball 8 (Figure 7). The saidoperating handle also prevents the rod from leaving the Sleeve.

The finger grip offers certain advantages over the ball handle,particularly due to the fact that it immediately indicates the operationof the rod and gives a sure engagement. The finger grip is fitted to therod with the arched portion extending on one side or the other accordingas to whether the device is intended for leftor rightgoing windows. Thearch-form of the engagement 8 may vary; the free end should be bent insuch a way as to eliminate the risk of clothes, curtains et cetera beingcaught therein. The re'-.. cess in the rod end for the engagement may bearranged horizontally instead of vertically.

In the window sash or the window frame, re-

spectively, there is provided a locking member in the form of afork-shaped projection provided with a notch 9, in which notchithe freeend portion of the rod is adapted to be insertedatv the. closing of thewindow. The bearing surface 9'.,.

lies at the same level as, or possibly'somewhat above the lower: surfaceof the rod in free position. In order to facilitate the insertion thereis provided a guide surface In. Different forms of locking members mayalso be employed. The rod is manufactured from some suitable metal ormetal alloy, and should preferably be resilient so as to facilitate itsmoving in and'out of lockingposition over the notch.

In Figures 1 to 3 (see particularly Figure 3) the sleeve 5 is shownrotatably mounted. in the legs of a U-shaped stirrup It or the likesecured to the window sash; According to Figures 4 and 5 the sleeve isturnable in a fitting l2 secured to the window sill. 5 indicates thebearing of the sleeve. I

The rod is mounted with play in such a way on a pin l3 secured to theend of a fork-shaped fitting I4 that the rod has a certain free motionrelatively to the fixing point in the vertical position and alsointheaxial direction, if desired. This is necessary in order to permit therod to sink so as to engage the stopping sleeve, 1.. e., to a. depth,corresponding to that of the recesses l, and it is also suitable inorder to avoid the exact relative adjustment of rod, stopping sleeve andlocking member 9 which else might be necessary at the mounting. Inaddition to the pin hole of'the rod end=having asomewhat larger diameterthan the pin in the axial direction of the rod the end I5 of the rodfacing the fork arms is formed with a rounded taper (see particularlyFigure 7). Thus, a constant'contact against the fork arms is ensuredduring the oscillating movements of the rod so that noise is avoided.

If desired, the surfacesl5 may be made spherical in order to enable auniversal movement of the rod if this should prove necessary in order toavoid jamming between rod and stopping sleeve orfor some other purpose.The pin hole is then accordingly modified.

In the neighbourhood of the fixing point, the recesses 1 areprovided'nearer to each other and then farther from each other; and thedistances are adjusted in such a way that the window may be stopped inpositions of about mutually equal distances around the arc in which therod moves.

If the device is to be attached to an existing Window, or possibly inother circumstances also, it may be necessary to insert spacing washersunder thefixing means for the rod or guide member or both so that saidrod and guide member may be in correct alignment with each other or withthe" catch'whenv the window is closed.

The length of the rod, the position of its fixing point and the positionof the sleeve are preferably adjusted so that an opening movement ofabout may be imparted to the window and so that the most suitable leverrelation is obtained. Thus, starting from closed window, the distancebetween the inner (hinge) edge of the window sash and the fixing pointof the rod should be larger than the distance between thesaid fixingpoint and that of the sleeve; the last distance, inits turn, beingsmaller than the distance be- ..tween the sleeve and the free end of therod.

Due to the fact that the pivot moves inwardly relatively to the free endof the rod, the leverage of said freeend increases with the movement of.the window towards the closing position correspondingly increasedturning moment with the operation of the window towards this position isobtained, and relatively less force is required for the said operation.

The function of the device is, in the first place, connected with theabove indicated lever relations so that the window may be operated bythe rod with, so to speak, less power consumption thaniby a direct gripon. the window. The device functions as follows. When the windiw' isclosed the, outer end of the control rod 3 is located in the notch 9;due to the above-stated lever moment of the rod and, to the fact thatthe rod rests closely against the edges of the hole of the sleeve aneffective securing of thewindow isensured 7 even if the other lockingdevices, if any, of the window are released. When opening the window oneraises the control rod from the locking posi- -,tion by engaging, orgrasping the operating handle, and moves the window inwards or outwards,respectively,: the rod gliding in the sleeve 5 during simultaneousturning of the sleeve. When the window hasbeen opened to the desiredextent the control rod is lowered or dropped so that the respectiverecess I will enclose the engagement portion 6 of the sleeve, the rodthus being locked and the window stopped in the intended open position,In order to release the rod from the locking positionone need only raisethe same towards the .upper edge of the. hole 4 and then the window maybe freely operated again by the rod. When the window is being closed theouter portion of the rod glides or is movedupwards along the guidesurface I0, and falls or is lowered into the notch 9 (Figure 3). I

Modifications of the embodiment shown are, of course, possible. Thus,the rod may have another shape than cylindrical and the recesses of therod may have other shapes. The stopping sleeve may be embodied andmounted in another suitable way than the one shown. i e

The device may be used in windows having simple as well as double(coupled) sashes, and also in vertically swingable windows whereby itshould be modified with respect thereto, and in doors of various kinds.

Having now described my invention, what I claim as new and desire tosecure by Letters Pattent is:
